"I really truly believe that pregnancy is not a time to have an excuse to eat donuts," the Supermarket Superstar host, 34, told Us exclusively at an event for Baby Jogger Vue strollers at baby boutique Bel Bambini in West Hollywood July 10. "I haven't had any cravings believe it or not!" George Clooney's ex added.

In fact, Keibler is eating healthier than ever. "[Pregnancy] is a time to be as healthy as you can be and build the foundation for your baby. I think that you should be even more conscious of what you're doing."

Keibler, who is due next month, went on to gush that she's had "the best year of my life," adding, "I'm so grateful for my life, my husband, the new baby on the way. Life is all about timing and everything happens for a reason. I literally wake up every day and say how grateful I am."

The blonde revealed she and Pobre "can't wait" to be parents and "everything's ready—the nursery is ready to go! … We've read a million books, [and] we did a full house detox [of anything unsafe.]"

The prepared parents-to-be have even already decided on a name for their baby girl. "It's a secret for now," Keibler says, "We just cannot wait to meet her. I feel like we have such a connection already. I feel like we intuitively talk to each other, and so I just can't wait to actually meet her."
